TORELIEF® CTP

With TORELIEF® CTP, you can achieve simple plate-making procedure and finer image reproduction.

Basic Structure of TORELIEF® CTP

Characteristic Advantages of CTP

1. Filmless plate-making

You can eliminate primitive plate-making faults with use of negative film, for example dust entrapment or light scattering.

2. Excellent Image Reproduction

Sharper dot, deeper reverse image, and finer halftone image can be reproduced with CTP, because of direct exposure to plates.
